Bird Facts



What defines a bird?

Birds are warm-blooded vertebrates with feathers, beaks, and lightweight skeletons. Most birds can fly, but some, like ostriches and penguins, are flightless. They lay hard-shelled eggs and are found in almost every habitat on Earth.

How many bird species are there?

There are approximately 10,000 known bird species worldwide, ranging from tiny hummingbirds to large ostriches. New species are occasionally discovered, adding to this incredible diversity.

Why do most birds sing?

Birds sing for various reasons, including attracting mates, defending territories, and communicating with other birds. Their songs are often species-specific and can vary depending on the time of year and environmental factors.

How do birds navigate?

Birds use a combination of the Earth’s magnetic field, the position of the sun and stars, and landmarks to navigate during migration. Some species even have a specialized protein in their eyes that helps them sense magnetic fields.

Can all birds fly?

No, not all birds can fly. Flightless birds, such as ostriches, emus, and penguins, have evolved to adapt to different lifestyles, relying on running, swimming, or other forms of locomotion instead.

What’s the world’s largest bird?

The world’s largest bird is the ostrich. It can grow up to 9 feet (2.7 meters) tall and weigh as much as 320 pounds (145 kilograms). Ostriches are flightless but are incredibly fast runners, capable of reaching speeds up to 45 miles per hour (72 kilometers per hour).
